“I'm so honoured to bring a medal home for Team GB. I never take that for granted, anything can happen in these races," Porter said.

“It wasn't my best performance. My start was awful, that was frustrating because that's one of the better parts of my race. All of us know you never go out there thinking who ran what earlier. It's all about delivering on the day, Nia showed that.”

Elsewhere in the afternoon session Luke Cutts finished eighth in the pole vault final with a best clearance of 5.65m.
